Abstract

FIELD: projectiles designed for use with a fixed round for artillery rifled and smoothbored systems of small and medium caliber.

SUBSTANCE: the projectile has a body with one or more driving or obturation band. The first from the projectile nose driving or obturation band is positioned in the head part of the projectile at a distance of 0.05-to-0.4 of the projectile length from its nose, the larger part of the projectile is positioned inside the cartridge case.

EFFECT: enhanced power of the projectile and the rate of fire.

Description

The invention relates to basic munitions for barrels, and more specifically to caliber artillery shells intended for use as part of unitary shots in small- and medium-caliber barrel artillery automatic reloading.

Well-known artillery shells for general purposes.

The closest analogue of the claimed invention is a well-known and widely used projectile designed for a unitary shot ([1], p. 41), consisting of a shell-shell, functional filling, for example, a burst charge, a leading belt, centering thickening, fuse. The lead belt of this projectile is located in the tail of the projectile. The projectile is secured in a unitary shot by tightly fitting (rolling, caulking, etc.) the tail of the projectile located behind the leading or obturating belt in the sleeve of the cartridge case ([1], p. 37).

The characteristic features of this projectile (prototype), due to the attachment system of the projectile in the sleeve, where, in fact, the projectile is a cantilever beam, “pinched” in the barrel of the cartridge case, are:

- a significant length of a unitary shot, since most of the projectile protrudes from the sleeve;

- a fundamentally low bearing capacity of the shell-shell junction inherent in the cantilever mounting scheme limits the length and mass of the shell; the realization of an acceptable load-bearing capacity of the shell-shell junction requires the shell to be made in the form of a relatively thick-walled metal structure, the mass of which is from 40% to 60% of the mass of the entire shot (see [1], p. 60).

The disadvantages of the prototype, as a consequence of the described features, are:

1) long strokes of the reloading system, due to the large length of the unitary shot, leading to a decrease in the rate of fire and an increase in the mass of the gun;

2) the limited power of the projectile at the target, due to restrictions on the length and mass of the projectile;

3) limited dynamic loads on a unitary shot, determined by the low bearing capacity of the shell-shell junction, limiting the rate of fire;

4) the presence in the ammunition from 40% to 60% of the “dead” cargo-shells, which is extremely undesirable, especially for transported artillery systems: aviation, armored, ship, etc.

The task of the invention is to increase the effectiveness of the “gun-ammunition” system by minimizing the above disadvantages of the known small- and medium-caliber artillery shells used in unitary shots.

Technical results that can be obtained by carrying out the claimed invention:

1) an increase in the power of the projectile at the target due to an increase in the length of the projectile while maintaining the caliber unchanged;

2) a relative decrease in the mass of the cartridge case, and consequently, either an increase in the number of shots without increasing the total mass of ammunition, or a decrease in the mass of ammunition without reducing the number of shots;

3) an increase in the rate of fire, a decrease in the progress of the reloading system, a decrease in the mass of the gun due to a decrease in the total length of the unitary shot and an increase in the bearing capacity of the shell-shell joint;

4) reducing the mass of the gun by reducing the caliber, while maintaining unchanged the power of the projectile at the target.

The essence of the invention lies in the fact that the artillery caliber projectile for a unitary shot, comprising a housing with one or more leading or obturation belts

- equipped with the first leading or obturating belt located from the projectile’s nose, located in the head of the projectile at a distance of 0.05-0.4 projectile lengths from its nose, with most of the projectile placed inside the shell;

- fixed in the sleeve using both its head in the zone behind the first belt and its tail.

The presence of signs that distinguish the claimed solution from the prototype, allows us to conclude that the claimed invention meets the criterion of "novelty."

During the search, no technical solutions were found that confirm the prominence of the distinctive features on the indicated technical results. This allows us to conclude that the claimed invention meets the condition of an inventive step.

The drawing shows a caliber projectile according to this invention as part of a unitary shot. The length of the projectile L. The first leading (obturating) belt 1 is located in the head of the projectile 2 at a distance A from the nose of the projectile. A = (0.05 ... 0.4) L. The projectile is compressed by the dulets B of the sleeve 3 in the zone behind the first, from the projectile nose, leading or obturating belt, and the projectile shaft B is fixed in the bottom of the sleeve.

Description of the design of the caliber projectile as part of a unitary shot

The installation of the first leading or obturating belt in the head of the projectile allows you to place most of it in the sleeve, which opens up the possibilities:

- reducing the total length of the unitary shot and, consequently, reducing the progress of the reloading system and thereby reducing the mass of the gun and increasing the rate of fire;

- increasing the length of the projectile and, consequently, its mass and the mass of its functional filling (explosive, pyrotechnic composition, etc.), and this is more power to the target;

- the implementation of a two-support shell attachment in the shell, in which the shell body, rather than the shell, becomes the main load-bearing element, which makes it possible to lighten the shell and increase the bearing capacity of the shell-shell joint. The increased load-bearing capacity of the “shell-shell” connection allows to increase reloading speeds, i.e. increase the rate of fire, and a lighter liner is either an increase in the number of shots without increasing the total mass of ammunition, or a decrease in the mass of ammunition without reducing the number of shots.

Thus, the technical solutions of this invention allow us to achieve the goal: improving the effectiveness of the “gun-ammunition" system.
